A Collaborative Project : Comparison and Validation of Earthquake Simulators

Project: Research project

Description

In fall 2009 and spring 2010, using this SCEC support, we will continue to participate in the Southern California Earthquake Center (SCEC) earthquake simulator workshops and code validation effort. We will run earthquake simulations for simple fault geometries (single fault) but also complex, state-wide (California) fault systems including tens to hundreds of faults. The specific parameters used in these simulations (e.g., fault geometries, frictional parameter, tectonic loading functions) will be discussed and defined during workshops and group meetings as well as conference calls. Informal group meeting will be held during the major geoscience conferences including the SCEC annual meeting, GSA fall meeting and AGU fall meeting. The resulting synthetic seismic catalogs are compared with results from other groups participating in this effort during these meetings to outline further progression in validating individual earthquake simulators. The participants of earthquake simulator workshops (including our group) will aim to identify metrics that characterize the success i.e., correctness of the simulator results. These metrics, particularly for large, state-wide models will be of statistical nature and should be comparable with natural seismicity. a. Run simple (single fault) simulations for comparing fault rupture between dynamic fault models and EQ simulators b. Run large (state-wide) simulations for comparing statistics and overall slip distribution with geologic and geodetic data.
